Abstract
A rotary arm-actuated pintle valve assembly having a pintle valve seat, a pintle shaft, and a valve head forming a pintle valve for regulating flow of gas through a valve body. The shaft extends through a port in a wall of the body. A rotary-arm actuator mounted to the body includes an oscillating motor and shaft. An arm mounted on the motor shaft engages the outer end of the pintle shaft and causes the pintle shaft to reciprocate to open and close the valve. The port permits the pintle to move back and forth radially during actuation of the valve. A floating bearing assembly at the port receives the pintle and slides back and forth as directed by the pintle, all the while maintaining a pneumatic seal around the pintle. A centering element is provided within the valve body to guide the pintle in mating the head with the seat.
